Description

Mild and rapid hair dye and preparation method thereof

Technical Field

The application relates to the technical field of hair dye cosmetics, in particular to a mild and rapid hair dye and a preparation method thereof.

Background

Hair dyes are of a wide variety and include temporary, semi-permanent and permanent hair dyes according to the degree of fixation. The permanent hair dye has wide application range due to high dyeing fastness and high dyeing durability. The permanent hair dye is an oxidation hair dye, which is formed by condensation reaction under the action of an oxidant to generate larger dye molecules after entering into a hair sebum layer through small molecular intermediates such as p-phenylenediamine, resorcinol and the like and a coupling agent, and is sealed in hair fibers, so that the effects of changing the color and fixing the colors are achieved, and the permanent hair dye has longer durability.

The hair dye generally comprises a hair dye paste A agent and a color developer B agent which are manufactured separately and stored separately, and are mixed according to a certain proportion and acted on hair when in use. Wherein the agent A contains a large amount of electrolyte including dye, antioxidant and other components, and an emulsifying system is commonly used in the market to prepare the agent A. The existing several common emulsification systems have the following defects:

(1) Nonionic emulsifying systems, which have poor tolerance and poor stability, are difficult to form paste if the dye amount of the system is high, and are easy to break and delaminate; if the dye consumption of the system is small, the coloring is difficult, the dyeing speed is low, and the dyeing effect is poor.

(2) The anionic and nonionic emulsifier system, which contains anionic surfactants such as AES and K12, has strong decontamination and degreasing capabilities, so that poor conditioning performance can be caused, hair is not smooth enough to wash after dyeing, and hair is easy to frizz after dyeing.

(3) The cationic and nonionic emulsifier system, which contains cationic surfactant with positive charges, has good conditioning property but slower color development, and needs more dye addition amount for obtaining full color in the same dyeing time, thus not only increasing the cost but also increasing the sensitization probability.

Disclosure of Invention

In order to solve the technical problem, the application provides an efficient emulsification system hair dye, which can be rapidly colored in the hair dyeing process, has higher color fastness after coloring, and has mild emulsification system components, good hair conditioning property and smooth and unhappy hair after use.

In a first aspect, the present application provides a mild and rapid hair dye, which adopts the following technical scheme:

the mild and rapid hair dye comprises an agent A and an agent B which are stored independently and mixed according to a volume ratio of 1:1 when in use, wherein the agent A consists of the following components in percentage by mass: 0.5-2% cationic surfactant, 0.5-2% nonionic surfactant, 0.1-1% anionic surfactant, 1-6% solvent, 0.5-3% pH regulator, 1.5-2.5% p-phenylenediamine, 0.1-1% meta-aminophenol, 0.1-1% resorcinol, 0.01-0.15% para-aminophenol, 0.01-0.12%2, 4-diaminophenoxy ethanol hydrochloride, 0.1-0.5% chelating agent, 0.2-1.5% antioxidant, 0.5-2% thickener, 0.5-4% grease, 0.1-1% perfume, 0.1-2% hair conditioner, and the balance water;

the agent B consists of the following components in percentage by mass: 1-6% of nonionic surfactant, 0.5-3% of thickener, 1-3% of grease, 10-20% of hydrogen peroxide, 0.15-1% of chelating agent, 0.1-0.5% of pH regulator, 0.05-0.3% of essence and the balance of water.

By adopting the nonionic surfactant, the anionic surfactant and the cationic surfactant at the same time and reasonably controlling the dosage of each surfactant, the hair dye is mild in use, the hair after dyeing is soft and not knotted, the hair dye has fast color development, good level dyeing permeability and fast hair infiltration.

The nonionic emulsifier system is easy to bring about the problem of poor emulsification effect, the anionic emulsifier has strong degreasing capability and can bring about the problem of poor conditioning property, and the cationic emulsifier has good conditioning property, but has slower color development and easily causes higher dye consumption. The three emulsifiers are mixed and used, the dosage of the three emulsifiers is controlled, and in practice, the phenomenon of reaction precipitation of the cationic surfactant and the anionic surfactant can be avoided, and the hair dye with quick color development and good mildness and conditioning performance can be obtained by combining the advantages of the three emulsifiers.

Preferably, the hair conditioner is one or more of polyquaternary ammonium salt, silicone oil, proteins, water-soluble oil, plant extract, etc.

Preferably, the cationic surfactant is a mixture of one or more of octadecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride and docosyl trimethyl ammonium chloride.

The raw materials specifically selected for the pH regulator are all conventional and commercially available, and are low in cost and easy to obtain, wherein the pH regulator in the agent B can regulate the acidity of the agent B so as to improve the storage life of the agent B.

Preferably, the chelating agent is one or more of EDTA-disodium, pentasodium pentetate, hydroxyethyldiphosphate, tetrasodium pyrophosphate and disodium hydrogen phosphate.

The chelating agent plays a role in capturing metal ions in the hair dye, and can avoid the influence of a small amount of free metal ions on the dyeing effect, thereby causing color deviation.

Preferably, the antioxidant is a mixture of one or more of sodium sulfite, sodium metabisulfite, ascorbic acid and salts thereof, and isoascorbic acid and salts thereof.

The isoascorbic acid, sodium isocyclonate and sodium sulfite are matched for use, so that on one hand, the oxidation of the dye intermediate can be prevented, on the other hand, the uneven dyeing of hair or the reduction of dyeing effect caused by too high oxidation speed can be prevented, and the oxidation of the dye intermediate after full diffusion in hair can be ensured.

Preferably, the thickener is one or a mixture of two of fatty alcohol and hydroxyethyl cellulose.

The thickening agent mainly plays a role in adjusting the viscosity of the hair dye, so that the agent A and the agent B can be uniformly mixed, and the use is convenient.

In a second aspect, the present application provides a method for preparing a mild and rapid hair dye, which adopts the following technical scheme: a preparation method of a mild and rapid hair dye comprises the following steps:

a1, mixing water, a chelating agent and an anionic surfactant, heating, adding p-phenylenediamine, m-aminophenol, resorcinol, p-aminophenol, 2, 4-diaminophenoxy ethanol hydrochloride, an antioxidant and a solvent, and stirring for dissolution to obtain a mixture A1;

a4, cooling to below 45 ℃, sequentially adding essence and pH regulator, homogenizing for 3-5min, cooling to below 30 ℃, and discharging after detection is qualified;

the agent B is prepared by the following steps:

b1, mixing a nonionic surfactant, a thickener and grease, and heating to obtain a mixture B1;
